Use a wide toothcomb to detangle your hair. Always detangle from the bottom, as you work your way up. To avoid tangling during the night, put your hair in a loose twist or bun.
You would need just one pack for a full head.
We do not recommend dyeing the hair as it is made of a high temp fiber and not actual human hair. Therefore, it does not have the cuticles present to absorb the color.
Depending on the individual the lifespan of high temp fibre differs and also the curly fibre is more likely to have a shorter lifespan than straight (3 to 6 months).
